The blister light box is a three-dimensional luminous word processing technology, which is made of acrylic material. It has the characteristics of high compressive strength, good light transmission, clear effect and durability, and is the first choice for many merchants. The blister light box is also a kind of light box, and it is also a common light box that is common in the streets.

  5. Plug in the power plug and close the main power switch to see if the light is normal. If there is a phenomenon that one side is bright and not lit, please disconnect the power supply first, unplug the plug, and check the lamp socket wire, whether the lamp is loose or not; Whether the input and output wires of the ballast are loose, etc.

  6. If the whole plastic light box is not bright, please check whether the leakage protector is closed, whether the wire connector inside the plug is loose, whether the pressure input and output connectors are loose, etc.;
